Celiac Testing

I don't see a support group for my area (NE Ohio), so I'll ask on here.

Hi! I'm Sarah, I'm brand new to this! I don't have insurance so I haven't been tested. I have family members who are diagnosed, and who passed from gastro cancer. I highly suspect I am celiacs or sensitive as well and have been trying to go gluten free. It is so difficult! Not just giving things up, but figuring out if gluten is in items! All the chemical names for different things that contain gluten. Its an overwhelming list!

Any information on where there may be free, or not so costly, testing would be great!
Also, I'm seeing stuff about different types of blood tests? What is up with that?

Any tips for recognizing gluten ingredients that aren't clearly labeled?
